OAR-OOUPLING.

SPECIFICATION forming part f Letters Patent No. 416,668, dated December3, 1889.

Application filed June 14, 1889. Serial No. 314,225. (No model.)

To all whom, it may concern:

' the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Car-Couplings; andI do hereby declare the following to rbe a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to whichv it appertains tomake and use the same.

My invention relates to car-couplings, and

has especial reference to improvements in that type of couplers known tothe trade as the Janney or master car-builders 7 Icouplerthe latter forthe reason that this type of coupler was adopted by them for use onrailways at their last annual convention.v

Theinvention will be hereinafter described, and particularly pointed outin the claims.

In the accompanying drawings, which form part of thisspecification,Figure 1 represents a plan view of my improved couplers;Fig. 2, a horizontal longitudinal section; Fig. 3, a

verticallongitudinal section through the cenv A at d', and isintersected by an angular surface e', at a tangent to the curved lined', which ter of one coupler, showing the hook in side elevation. Figs.4 and 5 are details of the hook and the latch.

tensions c d, which engage with rabbets or seats e f on thehead B, andeach of said seats extends back into the front end of the shank, asshownat g h in Fig. 3, and are seated at theirends in a transverselyconcaved seat z' in the shank.

On the rear side of the head B is a recess having angular walls k Z, toafford free lateral motion of the head on the shank in rounding curvesin the roadway. The head B and the 'shank are secured together by a pinC, which extends through apertures in both of, said parts.

D indicates the couplin g-hook, which is provided with recesses m m,which form seats for the extensions n n on one arm E of the head, and aAprojection or shoulder o, which ext-ends across the entire height ofthe hook, and engages with or abuts against the shoulder p on the arm Eand receives part of the shock in shunting cars, the shock beingdistributed upon Ithe curved walls gon the hooks, the circular front endfr of the extensions n fn, and the pin F, which secures the hook D tothe arm E of the head B. The hook is also provided with a rearwardextension s, which end, which bears againstone side of a gravity dog orlatch G, pivotally secured to one side of the head at a', is providedwith aweighted leverb, is curved at c', and projects up into the chamberv from `the under side of the head and locks the hook in coupledconnection with another similar coupling. V

The outer surface of the hook D is curved tangential or angular surfacec directs the adjacent hook againstthe rounded surface f on the arm H ofthe head B, from which it slides along the curved surface g of the headuntil the two hooks are iirlnly and securely inter` locked. v

As two couplings approach each other the Iirst point of impact orcontact is at h', opposite the pin F, when the couplings move laterally,and the two hooks slide upon the inclined surfaces e until they strikethe rounded portions f of the arms H, when the couplings again movelaterally and interlock the hooks. To uncouple, the gravity-levers b areraised by any suitable means, and the inner end of the dog withdrawnfrom the extension s, when, the hooks will disengage themselves;

To provide for coupling with cars having the ordinary link, a slot t' isformed in the front of the hook D, and a pin I passed vertically throughthe link. From the upper side of the shank A' projects a flange k forengaging with the timber of a car, and on the andahook pivoted in onearm of the head,

lower side thereof is a shoulder l', which bears against the stirrups incominonuse forsnpporting draw-bars.

By the construction shown each part A, B,

and D may be made Vof cast-iron, as sufficient strength is afforded bythe distribution of metal to resist the shock and strain common, torailway-service, and cars may be un-4 ooupled while standing or movingaround a curve in a roadway.

Having thus fully described my invention, what I claim is- Y l. In acarcoupling, a shank having a longitudinal aperture through it and achamber to receive the head of a bolt, an upper andv lower extension atthe front end, and a transversely-curved seat between said extensions,inA combination with a head having rearward vextensions fitting the curvedseat in the shank, .seats to receivethe extensions on the shank,

substantially Vas described.

2. In acar-coupling, a shank havingparallel sides and upper and lowerextensions at its front end, a head pivotally secured to the shank and-provided with a recess having .angular walls and seats to receive thelextensions on theshank, and a hookpivotally attached to one arm of thehead, substantially as described.

3. In a car-coupling, a shank having upper .and lower extensionsat itsfront end, and a laterally-swin gin g head pivotally secured to saidextensions, and a shoulder, as p, in combination withY a hook having ashoulder, as 0, a curved surface intersected by an angular surface onits front end, an extension having a curved surface conforming to theWall of the -arm of th'eehead, and a latch projecting through the bottomof the head and engag` ing-With the end of said extension on the hook,substantially as described..v

4. In a car-coupling, a shank having parallelsides, upper and lowerextensions at its front end, and a laterally-swinging head provided'witharrecess having angular walls on its rear side to engage with the shank,in colnl bination with -a Swinging hookzpivotally secured. to one arlnof the head, and provided with `:an .extension having a seat on one-sizde thereof, and af'gravity-latch projecting 'through the bottom ofthe head fand.pivotally secured to one side thereof, substantially asdescribed.

In testimonywhereofl aix my signature vinA presencev of two witnesses.
